Android :: How To Use Custom Item In Theme?
Jan 30, 2009
Could anyone post or point me to an example of using custom items in a theme? I've created a theme that uses custom attributes as item names, and I want to refer to those items in the code. I can see the theme is working because it also sets the android:windowBackground color. As a concrete example, I want an inactiveColor item in my Theme.GreenWithYellow to use in onDraw methods in my Views. I think this would be the right mechanism to use to have multiple color schemes for application specific purposes, but I would be happy to entertain other approaches, too.

I created a custom OverlayItem class so that I could essentially have one kind of OverlayItem whose Drawable marker would set itself depending on the state of some data that I pass into it. I have attempted to accomplish this by, on my first attempt, utilizing the setMarker method within the OverlayItem class. Once that did not work I attempt to override the getMarker method and have it return the appropriate marker to represent the data. Both of these attempts ended with nothing being drawn on the map...however if they are commented out the markers draw just fine (except they of course use the default marker, which isn't what I want). Here is my code for my custom OverlayItem class (the commented out methods I have tried and they have not worked):
private class MyOverlayItem extends OverlayItem {
private Context mContext; private MyData mData;
public MyOverlayItem(GeoPoint point, MyData data, Context context) {
super(point, data.getWhat(), data.getWhere()); this.mContext = context; this.mData = data;
/*if(data.getTemp() > 200) this.setMarker(res.getDrawable(R.drawable.icon_data_hot_l));
else if(data.getTemp() > 100) this.setMarker(res.getDrawable(R.drawable.icon_data_neutral_l));
else this.setMarker(res.getDrawable(R.drawable.icon_data_frozen_l));*/ }
/*@Override public Drawable getMarker(int stateBitset) {
Resources res = this.mContext.getResources(); if(this.mData.getTemp() > 200)
return res.getDrawable(R.drawable.icon_data_hot_l); else if(this.mData.getTemp() > 100)
return res.getDrawable(R.drawable.icon_data_neutral_l);
return res.getDrawable(R.drawable.icon_data_frozen_l);
}*/ }
Is there a way to do what I am attempting to do or do I need to make a unique OverlayItem class corresponding to each state of my data?

I have Implemented a custom ListView by extending LinearLayout for every row. Every row has a small thumbnail, a text and a check box. The list view is deployed properly and I can scroll and fling through it without any problems. But The ListView doesn't seem to respond to the setOnItemClickListener() at all, So I had to find a workaround by setting click listener in the getView of the Text inside every row which is obviously creating problem when I am trying to reuse the adapter. Does anyone have a solution?

I'm making a custom adapter so that I can display a list of items with icons which looks like the menu that comes up when you long click the home screen. For some reason though the list items are not clickable. The can be navigated to with the D-pad but they cannot be clicked in any way. I thought maybe the problem was with the AlertDialog I was using so I replaced a working adapter I had elsewhere but I have the same issue there. My adapter looks like this:
ArrayList<IconListItem> mItems; LayoutInflater mInflater;
public IconListAdapter(Context context, ArrayList<IconListItem> items) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mItems = items;
} public IconListAdapter(Context context) {
this(context, new ArrayList<IconListItem>());
} public void add(IconListItem item) { mItems.add(item);
notifyDataSetChanged(); return item;
} public void remove(IconListItem item) { mItems.remove(item); notifyDataSetChanged();
} @Override public int getCount() { return mItems.size();
} @Override public IconListItem getItem(int position) { return mItems.get(position);
} @Override public long getItemId(int position) { return position;
} @Override public View getView(int position, View convertView, ViewGroup parent) { View view;
if(convertView == null){ view = mInflater.inflate(R.layout.two_line_icon_list_item, null);
} else { view = convertView; } IconListItem item = mItems.get(position);
TextView lineOne = (TextView) view.findViewById(R.id.firstLine);
TextView lineTwo = (TextView) view.findViewById(R.id.secondLine);
ImageView iconImage = (ImageView) view.findViewById(R.id.icon);
lineOne.setVisibility(View.VISIBLE); lineTwo.setVisibility(View.VISIBLE);
iconImage.setVisibility(View.VISIBLE); lineOne.setText(item.getText());
if (item.getSubtext() == null) lineTwo.setVisibility(View.GONE);
else lineTwo.setText(item.getSubtext());
if (item.getIcon() == null) iconImage.setVisibility(View.GONE);
else iconImage.setImageDrawable(item.getIcon());
return view; }
And the XML it's inflating:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="6dip" >
<ImageView android:id="@+id/icon" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_marginRight="6dip" />
<LinearLayout android:orientation="vertical" android:layout_width="wrap_content"
android:layout_weight="1" android:layout_height="fill_parent" >
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1"android:gravity="center_vertical"
android:id="@+id/firstLine" android:ellipsize="marquee" android:inputType="text" />
<TextView android:layout_width="wrap_content" android:layout_height="0dip"
android:layout_weight="1" android:ellipsize="marquee"
android:id="@+id/secondLine" android:inputType="text" />
</LinearLayout> </LinearLayout>
When I say they are not clickable, I mean that they items do not highlight in orange when I press them nor does onItemClick ever get called. In my code I have this, a different adapter for another purpose and it works perfectly
this.foos= foos; fa = new FooAdapter(this.foos); fooList.setAdapter(fa);
// View the details for an item when it is selected
fooList.setOnItemClickListener(new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MyActivity.this, MyOtherActivity.class);
i.putExtra("foo", ((fooAdapter)arg0.getAdapter()).getItem(arg2));
i.putExtra("list_position", arg2);
MyActivity.this.startActivityForResult(i, 0);
} } );
But when I swap out the first 3 lines for
IconListAdapter ila = new IconListAdapter(this);
ila.add(0, "Test 1", android.R.drawable.ic_menu_mylocation);
ila.add(0, "Test 2", android.R.drawable.ic_menu_edit);
ila.add(0, "Test 3", android.R.drawable.ic_menu_search);
groupList.setAdapter(ila);
I t stops working.

I have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };

Is it possible to apply a custom background to each Listview item via the list selector?
The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible.
I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place.
For reference, this is the selector I'm using to try and get this working:
CODE:...............
And this is how I'm setting the selector:

As I am reviewing and prototyping my android project, I noticed that there is a view that has a list of items that are very customized. I have figured out most of my tools that I plan to use but I need some advice.
I have a list of items which can contain photos, some text to the right, an image to the bottom and more text below that. Very confusing I know. Each of these might be present for an item. The only thing that will always be there is the title.
So my question - what is the best way to create each custom list item view? I am thinking I have to use this getView to create each view. But when creating each view, is it best to 1) create a view dynamically and adding an image, for example, if it exists, or 2) create an xml file with all possible elements and hide them depending on the item?

I've a ListView with items containing information about places with a rating and the distance to the current location.
The items are sorted into groups:
Group 1: within 500m
Group 2: 500m - 1km
Group 3: 1km - 1.5km
Withing these groups the items are sorted by their rating.Now I put out these items via my custom adapter (extension of BaseAdapter) into the ListView, which works perfectly.
However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any idea on how to realize this?

I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.
Now, I would want something like this-
User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks)
I get to know the position of the row whose ImageView was clicked.
I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill).
Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.
I have provided an attribute in the Row XML like this-
CODE:..................
And in my code, I have a method like this:
CODE:..............
I can get the parent row (perhaps) but am not sure how to go further from here.

I'm trying custom the theme of Media Volume Controller (I don't know what it's called, just try to name it). It's something like a Toast with "Media Volume" title which appears when we press volume buttons (+ and -) in games. But I don't know which View it's, or it's a Toast, a Dialog. So far as I try, I could not find anything which refers it. Only Activity.setVolumeControlStream(AudioManager.STREAM_MUSIC)
to enable it in your Activity, and nothing more >_<
If someone know how to custom it, or just it's name.

I'm just beginning Android development, and I'm working to get a Custom list view with a checkbox working. I've created a base class that extends Activity, Created an Adapter and overrode the getView() method to add the checkbox to the list view. I'm assuming I need to do this because I need something equivalent to didSelectRowIndexAtPath from Obj C to update my model. Please let me know if there's an alternate way of doing this too Code...

I am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.
This is the item layout I made (post_item.xml):
CODE:........................
I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.
I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).
When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).
I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.
Here is my code for the Adapter:
CODE:..............
And this is the code to prepare the items:
CODE:.........................
Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?

I'm using the latest version of GO Launcher Theme Factory, and I've made a theme with around 30 icons, but I can't seem to add custom icons for other apps that aren't in GO's list. For example, I want to add a Nexflix icon for my theme, but I can't because when I double click on the add custom icon button, GO wants me to open an .apk file, not an image file. How to add a new icon to the list where it's actually an image file, or .apk file that I could download to my comp that has a bunch of custom icons listed (I'll make my own actual icons).

I just got a replacement DX due to random reboots.I read around on the forums that a factory reset would remove any custom themes as well as remove any signs of root.I was unable to achieve either with a factory reset and had to manually install the stock theme files, unroot, and then factory reset. Is this normal? Or was my factory reset not working properly?Is there a way to get back to "out of the box" without having to manually reinstall a stock theme and unroot?

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

I'm trying to create a basic AlertDialog using an activity with a theme of Theme.Dialog.What I want is for there to be a horizontal bar between the title and the message. However, the bar is not being resized correctly. Rather than being the width of the activity, the bar is the width of the message text. This means that if the activity is being expanded by the message, then the bar will fill the whole activity, so it looks correct. However, if the message width is less than the activity width, the bar only displays above the part of the activity with the text. I've tried every single combination of "fill_parent" and "wrap_content" that I can think of, and none of those work.I've also tried using RelativeLayout and placing the bar above the message text, but that also doesn't work. If I use the RelativeLayout approach and set the bar to fill_parent, it causes the activity to expand to fill the whole screen width, which is also undesirable. Ideally, I want the text placed, the activity width computed, and the bar resized to that width (without affecting it). Is there some way to flag a view to fill the parent view but not to affect its size?

I use themes in my apps, which generally just extend android:Theme and then set a bunch of styles. I use dialogs made from layouts, but since I set the theme for the application, they have inherited all of the regular styles and no longer carry a border, etc. My question is: How do I say, "I want everything to use this theme which extends Theme, except dialogs, which should use this other theme that extends Theme.Dialog"? It seems like that's how things work by default but when you set the theme to your own, you lose the dialog theme!

I've extended Theme.Dialog to use a different color as per the sample in the ApiDemos project but for some reason it does not use the theme properly in my project. I created a new project and it works perfectly fine there. The main problem here is that it does not show as floating in my project. Instead, it sets the rest of the screen black except for what would be the dialog window, where it uses the correct colors, etc. Any ideas? I am beating my head against the wall here.
